NAME
SoXtDevice -- abstract base class device for use with the SoXtRenderArea
INHERITS FROM
SoXtDevice
SYNOPSIS
#include <Inventor/Xt/devices/SoXtDevice.h>
Methods from class SoXtDevice:
virtual void enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)
virtual void disable(Widget w, XtEventHandler f, XtPointer data)
virtual const SoEvent * translateEvent(XAnyEvent *xevent)
void setWindowSize(const SbVec2s &size)
const SbVec2s & getWindowSize() const
DESCRIPTION
This is the abstract base class for devices in the Inventor Xt component and utility library. When a device is registered with an SoXtRen-
derArea, the device is able to generate events in the render area window.
METHODS
virtual void enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)
virtual void disable(Widget w, XtEventHandler f, XtPointer data)
Enable and disable the device for the passed widget. When enabled, the callback function f will be invoked when events occur in the wid-
get. data is the clientData which will be passed.
virtual const SoEvent * translateEvent(XAnyEvent *xevent)
This attempts to convert the passed X event into an SoEvent. If the event was not generated by this device, then NULL is returned.
void setWindowSize(const SbVec2s &size)
const SbVec2s & getWindowSize() const
Set and get the window size of the widget this device is registered for. This allows the device to correctly convert position informa-
tion from X window coordinates (origin at top left) to Inventor window coordinates (origin at bottom left). (SoXtRenderArea will auto-
matically call this method for each device registered on it whenever the window size changes.)
